Benefits of technology

[0022] The invention enhances the electrical connections among the lamp, the lamp holder and the power supply substrate without using soldering, and allows easy fabrication of a backlight assembly or a power supply module including a lamp, a lamp holder and the power supply subs

Problems solved by technology

However, the numbers of the lamps and lamp holders used in the backlight assembly increase with the size of the display panel, and a high number of lamps and lamp holders begins to pose disadvantages.
For example, with many lamps and lamp holders, the display device becomes heavier and fabrication time lengthens.
The soldering step tends t

Abstract

A lamp, lamp holder, and a power supply substrate that allow easy fabrication of a backlight assembly or a power supply module for a display device are presented. The lamp includes a lamp tube and an electrode that extends outside the lamp tube to form a lamp lead. The lamp holder includes a body for holding the lamp tube and a power supply member for providing voltage to the lamp lead. A power supply module includes a power supply substrate combined with a lamp holder holding the lamp. The lamp holders are fixed to fixing portions of the power supply substrate or to fixing holes of a connection plate. As the design allows easy separation of the lamp holders from the power supply substrate, building a backlight assembly or a display device is facilitated.
